of Albany, in f 'Albany and State of New4 Yorln'have invented certain new andv useful Impro'vements in Lubricators, of which the following is a specification.

My invention relates to -lubricato'rs, and

the object of my inventionis to provide an viewing-the-lub-ri'ca'ting fluid as it drops, and.x

ameans for causing the 'lubricatin fluid tobe 'delivered iirst to one together' with such ele. hereinafter I accomplishthese objects bymeans of the drawing, inwhich the figure puinp partly insect-ion. Centrally disposed in screw the adjusting plug, C. The cap', D, is placed on the oil cup-preferably provided into which the .endOf the adjusting plug, C, and preferably a por- 'l f the tube, B, projects.

In lthe tube, B, I place a valve, L, which' will be raised by theeffect of theairpressure eX-l erted throughthe fitting, K, and returned by the action of the spring, S, seated against the end ofthe valve and the end of the plug, C. Thisl movement of the valve, L, will cause an intermittent. movement of the -oil from thecup, A,'through the opening, into the pipe, J, whereby the-oil w1ll be' delivered drop by drop. -By manipulating the adjusting plug, C, in the tube,.B,I the frequency of the drops may be regulated. In .the ends ofthe tube, H, are placed glass or other transparent substance, g, g, making K. The obstruction inthe passagesire to secure by Aa peek-hole through which the operator Hof. `As thus arranged, when the ball is acted-upon by air from yone side of brake pump, It, on apparatus,

The operation vof the .is well known Aand the oil is thus delivered A to the cylinders of thepump in avery' positive and direct marmer.4 'My arrangement of y'th'e valve, L', is such that when the valve is raised by the-air. from the pump,`,it will be gradually depressed by tube, B, which will drop into the pipe, J', 'and befdelivered to the'cylinders of the a'ir'- pump, -t he"frequency of the dropping bev ing'regulatedby the plug, C, which can be adjusted to suit-,the necessities or 'requirementsv of the case. 4.
